Use osx_framework_user and osx_framework_library for Command Line Tools Python

[uranusjr]

A part of #9839 (comment).

[pradyunsg]

The change LGTM!

[uranusjr]

I’ve added a commit to incorporate the osx_framework_library scheme. @pradyunsg @rotu could you test if this quelch all warnings on the built-in Python on the following conditions?

• pip install --user
• pip install in a virtual environment
• sudo pip install (Is this possible? Don’t do this if you don’t want to, and make sure to install only something easy to remove afterwards.)

We're getting closer!

There are still significant problems with Homebrew's installed Python. Not sure if that's in scope but here's the output just in case:

Yeah Homebrew is hopeless, it’s impossible to fix it in pip so I’ll just add an exception for it and talk to them directly to resolve this.

The built-in one’s --user thing confuses me though. Would it be possible for you to upload sysconfig.py and distutils/command/install.py somewhere? Apple might be doing something wrong here…

[rotu]

You got it:
sysconfig.py.zip
install.py.zip

This also seems possibly relevant, found at /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/config-3.8-darwin
config-3.8-darwin.zip

Interesting… so it seems like osx_framework_user is just simply wrong (or delibrately breaking backwards compatibility). For all other schemes, sysconfig.get_path('include') is exactly one directory up comapred to distutils’s headers value, but osx_framework_user omits the python{py_version_short} part and is two directories up.

I guess all we can do is bubble this issue to CPython, and add an exception to suppress the warning for now.

[sbidoul]

I removed from the 21.1.1 milestone (replaced by #9912).

[uranusjr]

I’ve forwarded the os_framework_user issue as b.p.o-43948. No response as of now though, I’ll probably just create a PR to “fix” this to force to conversation forward.
